Applied online through my university and interviewed on-campus for an internship position. Very standard, generic behavioral interview. Interviewer asked for answers to be in the STAR format. About 30 minutes.

On campus interview. It mainly focused on personality test and also behavior questions. It took about 40 minutes. The people are very nice and the interview was well-organized.

The hiring process was quite straightforward. It was a one on one interview with the HR and basic questions like why you want the job and why specifically halliburton were asked. I met them in a career fair and I got an interview slot with them. They are a very good company and their employees are very courteous and reply promptly to any queries. The office is located in an industrial area and consists of both the office space and a manufacturing/testing facility.
